MATCH COMPOSITION- SPECIFICATION forming part of Letters Patent No.779,674, dated. January 10, 1905. Application filed May 7,1904. SerialN'o. 206,855.

To a whom it may concern: I

Beit known that I, HENRY S mian, a subject of the Emperor of Germany,and a resident of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful- Improvements in Match Compositions, of

character known in the. art as non-poisonousthat is to say,the fumesthereof are practically non-poisonous to attendants handling the samewhile the fumes of yellow phosphorus, commonly employed inmatchcomposition, are very poisonous. Hitherto the use of amorphousphosphorus has been substantially con fined to safety-matches, in whichthe amorphous phosphorus, or a preparation containing it, has been usedon the prepared surface on which to strike the match, the matchcomposition containing the potash necessary for producing ignition.Amorphous phosphorus employed in the match-head has hitherto resulted ina composition which has required so much friction to ignite as to makethe matches practically valueless. I have. discovered,

however, that scarlet phosphorus when united in the proper proportionswithchlorate 0f potash and other ingredients will produce a highigradematch composition which will readily ignite,which is not easily affectedby dampness, and which is of a non-poisonous character.

Incarrymg out my invention Ilemploy chlorate of potash, powdered sulfur,and soar let phosphorus in the proportion of about 'one' pound ofscarlet phosphorus to ,3 of a pound .ofpowdered' sulfur and 4.5 poundsof chlorate of potash. These ingredients I mix together,

and" alsoj'preferably i'nix therewith certain other material"such asplaster-of-paris, oxid of zinc, whiting, and the like, and. an abrafdantmaterial such as powdered glass, sand,

or the like-and a fluid bin'densuchas glue or gum-arabic, dissolved inwater. The whole being mixed together in the proper quantities forms ahigh-grade match composition. The following is a formula'which I haveemployed with successful results: glue, thirty two pounds; chlorate ofpotash, ninety pounds;

powdered glass, forty-two pounds;-p laster-ofpar geight pounds; oxid ofzinc, eight pounds; whiting, 'four pounds; powdered sulfur, six

pounds; scarlet phosphorus, twenty pounds,

In making up the composition 1 first dissolve the thirty-two pounds ofglue in about sixty pounds of water. Then I- mix the remainingingredients with about twenty pounds of water and finally'mix the massso formed with the dissolved glue. The-twenty pounds ofwater employedfor first dampening the dry powdered materials may be cold, while thewater employed for dissolving the glue should of course be warm, and thetemperature of the entire mass during mixture must be-warmin order toprevent the glue from setting.

The chlorate of potash, powdered sulfur, and

scarlet phsph'orus in about the quantities stated together form acomposition readily ignited. The plaster-of-paris, oxid of zinc, andwhiting are employed as filling and'binding material, while the powderedglass is added for the pur-' pose'of increasing the susceptibility ofthe mixture to inflammation by friction. The glue .is used in thiscomposition, as inmost such compositions, for the purpose of binding thewhole material together and causing it to adhere to match-splints.

Itwill of course be understood that the dry filling and bindingmaterial---such as the plaster-of-paris, oxid'of zinc, and -whiting-.maybe 7 varied considerably, while still retaining the generalcharacteristics of my composition, as

also other material, such assand, may be sub- I stituted for thepowderedglass, and other materials, such as gum-arabic, may leesubstituted for the glue.

What I -claim is-.

. 1. The herein-described'match composition,

comprising [a mixture of scarlet phosphorus, powdered" sulfur andchlorate of potash, in about the proportion of one part ofscarlet and4.5 parts of'dhlorate ofv potash, together with abinding material,

.95 phosphorus to.3 of 'aipart of powdered sulfur,

10 comprising a mixture of and 4.5

2. The herein-described match composition comprising a IDlXt-UPB ofscarlet phosphorus,

powdered sulfur, and chlorate of potash, in

about the proportions of one part of scarlet phosphorus to .3of a partof powdered-sulfur and 4-.5 parts of chlorate of potash, together Withan ahraclant material, and sufficientglue to bind the mixture together.

3. The herein-described match composition scarlet phosphorus, powderedsulfur, and chlorate of potash, in about the p21 portions of one part ofscarlet phosphorus to.3 of a part of powdered sulfur parts of chlorateof potash, together with an abradant material, binding and filling;material and glue.

4. The herein-described match composition comprising a mixture ofscarlet phosphorus, powdered sulfur, and chlorate of potash, in

about the proportions of one part of scari t p 'iosphorus to .3 of apart of powdered sulfur and 4.5 parts of chlorate of potash, togetherith an abradant material, a relatively small quantity ofplaster-of-paris,

oxid of zinc, and

i/ i i i Whiting, and sufiicient glue to properly bind the materialtogether.

5. The herein-described match composition, comprising a mixture ofscarlet phosphorus, powdered sulfur, chlorate of potash, an abradantmaterial, plaster-ofparis, oxid of zinc, whiting and a binding material,combined together in substantially the proportions above set forth.

6. Theherein-descrihed match composition comprising the followingingredients, in about the proportions stated: Twenty parts (by Weight)of scarlet phosphorus, six parts powdered sulfur, ninety parts chlorateoi potash, forty-two parts powdered glass, eight partsplaster--ot'-paris, eight parts OXid of zinc, four parts Whiting, andthirty-two parts glue, sulostanti lly described.

In ness whereof l have hereunto set my hand this 6th day of May, 1904;.H ENRY CTAIER.
